الملخص

الغرض من هذه الدراسة هو التحقق من سلوك القص للعتبات الفيروسمنية المجوفة المصنوعة من ملاط أسمنتي ذاتي الرص مسلحة بأنواع مختلفة من التعزيزات المعدنية (شبكة سلكية حديدية) وغير معدنية (شبكة الألياف الزجاجية). يتكون البرنامج التجريبي من صب ثمانية عتبات فيروسمنية بأبعاد 150 × 225 × 2000 مم وبسمك 50 مم من الفيروسمنت ولب من الفلين البوليسترين 50 × 125 مم. كانت متغيرات الدراسة تشمل نوع التسليح للقص وعدد طبقات الشبكات السلكية (واحد، اثنان، ثلاثة). أظهرت النتائج أن الحمل الاقصى للعتبات المسلحة بعدة طبقات من شبكة الألياف الزجاجية (واحد، اثنان، ثلاث) انخفض بنسبة (3.27٪، 16.52٪، 9.38٪) على التوالي، مقارنة بالعتبات المسلحة بطبقات من شبكة أسلاك الحديدية (واحد، اثنان وثلاثة). الا ان الحمل الاقصى لهذه العتبات ازداد بنسبة (33.71٪، 73.28٪، 122.11٪) على التوالي، مقارنة بالعتبات غير المسلحة للقص. كما ان الحمل الاقصى للعتبات المسلحة بطبقات من الشبكات السلكية الحديدية ازداد بنسبة (38.23٪، 107.56٪، 145.09٪) على التوالي، مقارنة بالعتبات غير المسلحة للقص فقط بالمونة الأسمنتية. طاقة الليونة والمتانة للعتبات المسلحة بعدة طبقات من شبكة الألياف الزجاجية (واحد، اثنان، ثلاثة) انخفضت بنسبة (1.68٪، 2.11٪، 2.68٪) و (29.39٪، 25.91٪، 16.06٪) على التوالي، مقارنة بالعتبات المسلحة بعدة طبقات من شبكة أسلاك الفولاذ (واحد، اثنان، ثلاثة). أدى استخدام الشبكات الفولاذية والزجاجية بدلاً من الركائب إلى تقليل انتشار الشقوق وعدد الشقوق وعرض الشقوق، خاصة في الحزم باستخدام طبقتين وثلاث طبقات من الشبكات. كما أظهرت النتائج أن استخدام الألياف الزجاجية أو شبكة الأسلاك الحديدية في تقوية الكمرات المجوفة بدلاً من الركائب الفولاذية له تأثير جيد على الحمل الاقصى والانحرافات وأنماط الشقوق وإجهادات القص، على الرغم من افضلية العتبات المقواة بشبكات حديدية بشكل واضح.
